I wouldnt give too much weight to their projections, The Meg had a higher opening weekend than their complete domestic forecast for that movie.
I think The Predator will probably land around 80 - 90m domestic, followed by a 150 - 180m foreign, depending on a China release. The movie has good buzz going, people seem excited, they have a good release date, not much competition, i think this movie can do really good.
